How To Update The Browser On A Visual Land Prestige Pro 7d Tablet

xdrc45 · Mar 22, 2014

This is a tutorial on how to install TWRP or CWM custom recovery on the Visual Land Prestige Pro 7D. Installing a custom recovery on the Pro 7D gives yous the power to perform nandroid backups and nandroid restores to the device. This is a great feature in the event that that something should become wrong on the tablet and you get force closes, reboots, stuck in a boot loop and etc..
You tin can and so restore the tablet to a nearly factory status with a backup. With these custom recoveries you can also install flashable zips, mods, tweaks, firmware update zips and custom Roms when and once available. The Pro 7D has a Stone Chip Processor, a RK3066 to be exact and thankfully the Pro 7D too has a valid kernel in the kernel division... So what does that mean? Basically it allows for an easier installation of a custom recovery.

You do this at you Own Hazard. I take NO responsibility for your device if something should happen to get incorrect during the process and your device bricks, turns into a paperweight and your spouse leaves you!

Before you begin I highly recommend that you make a backup of your device using the modified RK 2.1 tool with full and like shooting fish in a barrel directions on how to make the backup from here -
Bankroll upwardly your RK device (ROM) with the new RK 2.1 tool

To kickoff -
Your device needs to be Rooted. Y'all can follow my Pro 7D rooting tutorial if you oasis't rooted It nonetheless, from here-

Download the custom recovery of your selection, either TWRP or CWM from hither -

For TWRP the recovery is based on the devices resolution. The Pro 7D's resolution is 1024 10 600. So yous'll demand to download the Generic unofficial TWRP v2.7.0.0 1024 x 600 RK3066 from here -
TWRP 2.vii.0.0 For Rockchip'south

Also you need to download the "flash_image file" for TWRP from here -
Dev-Host - flash_image - The Ultimate Free File Hosting / File Sharing Service

For CWM merely download the RK30GENERIC_CWM.zip from here -
CWM-based Recovery images for RK3066 devices | androtab.info

Once you've downloaded the recovery that you want, create a new folder on your PC's desktop and proper name it something similar "Pro 7D recovery" Place the downloaded CWM recovery zip into the Pro 7D recovery folder and extract it in that location with a plan similar 7zip.
For TWRP just identify the TWRP_2.seven.0.0_1024x600_rk3066.img and the flash_image file within the Pro 7D recovery binder.

Inside the extracted CWM recovery goose egg we will be using but 2 files.
1. flash_image
ii. recovery.img.

In TWRP we only have -
1. TWRP_2.7.0.0_1024x600_rk3066.img
2. flash_image

You will demand to rename the TWRP_2.vii.0.0_1024x600_rk3066.img to just "recovery.img" (without the quotes)

For the side by side part you lot will need to download from the play shop a File browser like "Root Browser" and a Terminal Emulator, "Rom Tool Box Calorie-free" has both a file browser and a concluding emulator in it, or you tin can employ the Android SDK with adb setup and working on your PC. I'k non going to become into that part of setting up the Android SDK and adb. Merely Google it, there are plenty of proficient tutorials on information technology.

Now for the actuall installation of the recovery -
Connect the Pro 7D to your PC with USB debugging enabled and open a command prompt.
If your familiar with adb commands and then just adb push the flash_image file to the root of the "data/local binder on the tablet and adb push the recovery.img to the root of the "internal sdcard" and set permissions - (each line is a new command and make certain your spacing is exact or it volition not work properly)

adb shell
su
adb push flash_image /data/local
adb button recovery.img /sdcard
chmod 755 /information/local/flash_image

If your not familiar with adb commands then but put the recovery.img and flash_image on your internal sdcard. Open your Root Browser, click and hold on the flash_image file, select "Move" and then navigate to "data/local" and and then paste the file here. Once you paste the file, click and agree on the flash_image file again and select "Permissions" and change the permissions to 755 by selecting the iii cheque boxes (Read, Write and Execute) on the tiptop line "Owner" and on the second line "Grouping" and and then on the third line "Other" select just Read and Execute and then save.

Now open up Terminal Emulator or command prompt so type these commands, (each line is a new command and make certain your spacing in the commands are exact otherwise information technology volition not work properly) -

adb shell
su
data/local/flash_image recovery /sdcard/recovery.img

If yous put the commands in correctly it volition say - "wrote recovery partition" and you have successfully installed the new custom recovery.
Proceed Terminal Emulator/command prompt open and blazon-

reboot recovery

The device will reboot to the newly installed custom recovery. I highly recommend making a backup at this point and your done!

Booting to recovery on the Pro 7D is a huge pain using the push button combination or having to use adb reboot recovery every fourth dimension, so I recommend that yous to install the RK Reboot app from here -
Reboot App
To install the Reboot app, on the Pro 7D you will have to become to "Settings" - Security and select/bank check "Unknown Sources" to allow installation from an unknown source. And then employ your Root Browser, navigate to the sdcard - downloads, click on the Reboot app and choose install.

Hope you enjoyed the tutorial... If so Please Click the Thanks Button.

This is Not whatsoever of my piece of work.... I just simply put this guide together for your benifit.
